Royal Enfield Swingarm Needle Roller Bearing - 148275/B - 1 Piece

Product Introduction

Royal Enfield 148275/B is the genuine needle roller bearing used at the swingarm pivot in the matching rear-suspension assembly. Also searched as a swingarm bearing or swing arm needle bearing, it supports movement around the correctly matched bearing sleeve.

Documented applications include Interceptor 650, Continental GT 650, Bear 650, Himalayan 450 and Guerrilla 450. This listing supplies one bearing. The checked catalogue arrangements require two of this bearing, so order quantity 2 when renewing both positions. Sleeves, end cups, seals and other pivot parts are separate.

Part Identification

What This Product Is

An individual needle roller bearing for the matching swingarm pivot. It is the bearing element, not the separate smooth bearing sleeve or a rubber bush. Identify the exact position in the rear-suspension diagram before dismantling or ordering.

What This Product Is Not

• Not a complete swingarm bush kit or pivot rebuild set.
• Not a pair: two bearings required on a motorcycle does not mean two supplied in this listing.
• Not the separate bearing sleeve, end cup, spacer, pivot spindle or spindle nut.
• Not a wheel bearing, steering-head bearing, shock absorber rubber bush or universal suspension-linkage bearing.
• Not an interchangeable replacement for every 26 mm, 33 mm or 35 mm OD needle bearing used elsewhere in Royal Enfield suspension assemblies.

Key Features

• Genuine Royal Enfield needle roller bearing reference 148275/B.
• 29 mm outside-diameter catalogue specification.
• Used in documented swingarm applications across selected 650 and 450 models.
• Sold individually for quantity-controlled repairs.
• Separate bearing and sleeve selection allows inspection of all pivot wear surfaces before rebuilding.

Royal Enfield swingarm needle bearing, swing arm pivot bearing, rear suspension needle roller bearing, swingarm bush bearing, 148275/B, 148275B, 148275, 22x29x30 bearing. A buyer may call it a swingarm bush, but this part is a needle roller bearing.

Confirmed Compatibility

Model books may display the base number without the suffix. Order exact 148275/B and verify the current VIN-specific EPC where a revision or replacement swingarm is involved. The documented catalogue editions do not establish an uninterrupted all-years or every-market range.

Fitment Requires Verification

Not Compatible / Do Not Order For

• Do not use this 29 mm OD bearing in a housing specified for a different bearing diameter or width.
• Himalayan 450 drop-link bearing RAR00137 and 35 mm OD bearing RAR00113 are separate components; this is not a complete linkage-bearing replacement.
• Guerrilla 450 drag-link bearing RAR00589 and 35 mm OD bearing RAR00113 are different references.
• No application is established here for Meteor 350, Hunter 350, Classic Reborn/J-Series, new Bullet 350, Goan Classic 350, older UCE 350/500 or Continental GT 535.
• Do not order a needle bearing when the worn item is only the sleeve, end cup, shock bush, wheel bearing or another suspension pivot.

Part Number / Revision / Supersession Notes

This listing retains the full number 148275/B. Unsuffixed 148275 is used as the base reference in specialist model books. No automatic supersession from a different numbered bearing or another suffix is claimed.

The current dealer description and multiple bearing references support the 29 mm OD specification. Some older master lists carry a conflicting dimension string. Confirm the actual packet and bearing before pressing it into the housing; do not force a dimensional mismatch.

Similar Parts Comparison

When Should This Part Be Replaced?

Inspect when the swingarm shows confirmed pivot play, rough or notchy movement, binding, corrosion or damaged rollers, or when a strip-down reveals worn bearing surfaces. Water ingress, damaged sealing parts and incorrect lubrication can contribute to wear.

Rear instability, clunks or creaks can also come from wheel bearings, tyre condition, loose fasteners, shock mounts, linkage bearings or chain adjustment. Diagnose the source before ordering. Do not continue riding with unsafe suspension play or binding.

Recommended Related Parts to Check

• Both swingarm pivot bearings and their housing condition.
• Bearing sleeves for pitting, scoring, corrosion and loss of the required running surface.
• End cups, seals and spacers for damage or incorrect assembly.
• Pivot spindle, washers, nut and any one-time-use fasteners specified by the workshop manual.
• Other linkage bearings on Himalayan 450 and Guerrilla 450; the same rear-suspension page contains several different bearing sizes.
• Model-specified grease, assembly clearances and final swingarm movement.

What’s in the Box

1 × Genuine Royal Enfield needle roller bearing, part number 148275/B.

Bearing only. A second bearing, sleeves, seals, end cups, spacer, swingarm spindle, washers, nut, grease and tools are not included. Order 2 bearings for the two documented positions when the repair requires both. This is not a full swingarm rebuild kit.

Installation Notes

Professional installation is recommended. Support the motorcycle securely and follow the exact model workshop procedure for swingarm removal. Identify each bearing position, record spacer and seal orientation, and compare the new part and packet reference before pressing it in.

Inspect the housing and sleeve; fitting a new bearing around a damaged running sleeve may leave play or shorten service life. Use a suitable driver and support the housing so pressing force reaches the correct bearing shell without damaging the rollers. Do not hammer through the rollers or use the pivot spindle to force the bearing into place.

Use the prescribed bearing depth, lubricant, seals, tightening sequence and model-specific torque values. No universal torque is supplied with this listing. After assembly, verify free swingarm travel, absence of play or binding, wheel alignment and correct chain adjustment before a controlled final inspection.

Before You Buy / UTH Order and Return Policy

Confirm exact 148275/B, the swingarm pivot location, nominal dimensions and required order quantity. Inspect related sleeves and sealing parts before deciding whether one bearing, two bearings or a separately assembled rebuild kit is needed.

Order cancellation is not available once processing has started. Correctly supplied spare parts are generally not returnable for wrong selection, incorrect diagnosis, mechanic recommendation, fitment mismatch or change of mind. Wrong-item, damaged-item or missing-item claims require a complete unboxing video and must be raised within 24 hours of delivery. Retain the part label and packaging for any claim.

Frequently Asked Questions

What is Royal Enfield 148275/B?

It is a needle roller bearing used at the swingarm pivot in the matching rear-suspension application.

Is one bearing or a pair supplied?

One bearing is supplied. Order quantity 2 if the repair requires both documented positions.

What is its size?

The dealer description is nominal 22 × 29 × 30 mm, and model books identify 29 mm OD. Match the packet and removed bearing before installation.

Why do some old lists show 22 × 28 × 20?

Published descriptions conflict. Do not buy or install by that old dimension string alone; verify exact 148275/B, bearing markings and the actual housing.

Does it fit Interceptor and Continental GT 650?

Yes, documented applications include both models. Confirm the model generation and current VIN-specific EPC.

Is Bear 650 included?

Yes. The checked Bear 650 Euro 5+ parts book lists base 148275 at rear suspension position 20, quantity two.

Is it also listed for Himalayan 450 and Guerrilla 450?

Yes. Their checked model books list base 148275, quantity two. Other bearings in the same suspension system have different references.

Is it the Himalayan 450 drop-link bearing?

No. The 26 mm OD drop-link bearing RAR00137 is separate. This is the 29 mm OD bearing reference.

Will it fit Himalayan 411 because Himalayan 450 is listed?

Do not transfer that fitment. The 411 suspension uses different bearing references and needs its own EPC check.

Are sleeves, end cups or seals supplied?

No. This listing supplies only one bearing; all separate pivot and sealing components must be ordered as required.

Does it fit every Royal Enfield 650?

No blanket 650-platform fitment is claimed. Super Meteor, Shotgun and Classic 650 require their own exact parts checks.

Will replacing it cure rear-end movement or noise?

Only if inspection identifies this bearing as the cause. Sleeves, wheel bearings, shock mounts, linkage parts and other faults can produce similar symptoms.
